第二届全国岩土力学与工程标准化发展高端论坛在武汉召开华海清科获专利，抛光保持环达到目标形状后自动停止修整
11月6日，华海清科（688120）的发明专利《保持环修整装置、化学机械抛光单元及其控制方法和化学机械抛光设备》获授权，申请号为CN202511705507.1。
在化学机械抛光设备中，保持环的接触面也需要磨削修整。专利把修整盘、形状检测部件和控制器放进同一控制流程，抛光头使保持环与修整盘相对转动，检测部件取得被磨削面的形状。控制器确认形状达到设定条件后停止转动。停机依据是实际检测结果，目的是避免在形状已经合格后继续消耗修整资源。
截至此次授权消息披露时，华海清科今年获得的各类专利授权共99项，比上年同期增加22.22%。在2026年上半年，公司研发投入为2.75亿元，同比增长12.59%。企业知识产权记录中，华海清科股份有限公司名下可查到896条专利信息和39条著作权信息。
